Polarisation Beam Combiner/Splitter (PBC/S)

The Polarisation Beam Combiner/Splitter is a compact high performance lightwave component that combines two orthogonal polarisation signals into one output fibre. The most common application is to combine the light of two pump lasers into a single fibre to double the pump power to an Erbium-Doped Fibre Amplifier (EDFA) or a Raman Amplifier. The typical configuration uses two PM fibres for the input and the SM fibre for the output. The device can also be used as a beam splitter.

Polarisation Beam Isolator & Combiner/Splitter (IPBC/S)

The Isolator Polarisation Beam Combiner/Splitter is a compact devices which provides both polarisation beam combining and optical isolation in one integrated component.
